<span>Question: What is the algebraic expression for "the difference between eleven times a number and four"?
</span>
How?: Well when he says, "The difference" you would be subtracting. When it says "Eleven times a number" you will multiply 11 times x. X stands for the unknown number.

Answer: It should look like 11x-4

HOPE THIS HELPS! ^_^

Lera25 [3.4K]

Answer:

A. We have extremely strong evidence to reject H0.

Step-by-step explanation:

Let P be the proportion of non-retirees in 2015 who did not think that Social Security would be able to pay a retirement benefit by the time that they retire.

According to the data null and alternative hypotheses should be:

$H_{0}$ : P=0.60

$H_{a}$ : P<0.60

Test statistics is -4.29 and p-value of the statistics is p<0.001

At every significance levels higher than 0.001, we can reject the null hypothesis since p<0.001.

For the functions f(x) = x^2+ 8x + 2 and g(x) = -5+9, find (f•g)(x)and (f.g)(-1).

Ne4ueva [31]

Answer: (f·g)(x) = -5x³ - 31x² + 62x + 18

(f·g)(-1) = -70

(fog)(x) = 25x² - 130x + 155

(fog)(-1) = 310

<u>Step-by-step explanation:</u>

f(x) = x² + 8x + 2 g(x) = -5x + 9

(f·g)(x) = (x² + 8x + 2)(-5x + 9)

= -5x³ + 9x²

- 40x² + 72x

<u> - 10x + 18</u>

= -5x³ - 31x² + 62x + 18

(f·g)(-1)= -5(-1)³ - 31(-1)² + 62(-1) + 18

= -5(-1) - 31(1) - 62 + 18

= 5 - 31 - 62 + 18

= -70

****************************************************************************************

(fog)(x) = (-5x + 9)² + 8(-5x + 9) + 2

= 25x² - 90x + 81

- 40x + 72

<u> + 2</u>

= 25x² - 130x + 155

(fog)(-1) = 25(-1)² - 130(-1) + 155

= 25 + 130 + 155

= 310

<em>It wasn't clear if you wanted multiplication or composition so I solved both.</em>

Changing Bases to Evaluate Logarithms In Exercise, use the change-of-base formula and a calculator to evaluate the logarithm.

Ymorist [56]

Answer:

$\frac{3}{2}$

Step-by-step explanation:

Changing Bases to Evaluate Logarithms

$log_{16}(64)$

Apply change of base formula'

$log_b(a)= \frac{log a}{log b}$

log term should be the numerator and denominator is the log base

$log_{16}(64)$

$log_{16}(a)= \frac{log 64}{log 16}$

64 is 4^3 and 16 is 4^2

$log_{16}(a)= \frac{log 4^3}{log 4^2}$

Move the exponent before log

$\frac{3log 4}{2log 4}$

top and bottom has same log so cancel it out

$\frac{3}{2}$
